Redonkulousaurus is an extension of the word "redonkulous," (popularized by the O.C.'s Seth Cohen) and serves to hyperbolize the already-supercharged fictional word. It was first used by Yula to describe her massive textbooks. Redonkulousaurus can be used as both a noun and adjective to describe something so utterly absurd, that it goes beyond the span of human imagination.
She has, like, $300 in her wallet. That's redonkulous.

Your mom is a friggin' REDONKULOUSAURUS. How many pizzas does she eat a day?

That textbook is REDONKULOUSAURUS.
